KERN IoP | ENERGY · ENERGY MEASUREMENT FOR INJECTION MOULDING
See where your injection moulding cell consumes energy.
Measure the injection moulding machine and your selected peripherals simultaneously. Separate their consumption, establish baselines and understand what happens within the cell before deciding where to intervene.
One machine or a complete cell · Three-phase and single-phase supplies · Expandable configuration
Machine and peripheral measurement within a common measurement boundary.
◉
Simultaneous measurement
Injection moulding machine and peripherals over the same operating periods.
↯
Three-phase and single-phase
Supplies with different electrical configurations, according to the installation.
↗
Historical data and baselines
Record trends to compare periods and conditions.
◎
Process context
Integrate cycle or production signals where required.
CELL ENERGY VISIBILITY
Locate the loads behind the plant’s total energy bill.
In an injection moulding cell, peripherals may operate under different conditions from the machine. Separating the measured loads identifies which equipment uses energy and when.
01 /
Combined consumption
A combined total leaves the contribution of each item of equipment unresolved.
02 /
Loads outside production
Some auxiliaries may continue drawing energy while idle or during downtime.
03 /
Decisions needing a baseline
A baseline is needed to verify the result of an intervention.
ENGINEERING INTERPRETATION OF MEASUREMENTS
Comparison requires measuring each supply and identifying the operating conditions during the analysed period.
01
Measure
Capture power and energy from each selected supply during operation.
02
Add context
Relate consumption to machine states, cycles and production where those data are available.
03
Compare
Establish baselines and compare technically equivalent operating conditions.

Relate energy to production when reliable production data are available.
With a defined measurement boundary and verifiable production data, the system can calculate normalised indicators. These indicators require both electrical measurements and the relevant production data.

PLANT APPLICATIONS
Questions worth answering with data.
Which equipment consumes the most?
Identify the distribution across measured loads.
What continues consuming energy during downtime?
Analyse defined idle periods.
Did consumption change after the intervention?
Compare against a baseline under equivalent conditions.
Which condition demands more power?
Compare power and its behaviour over time.
How is energy distributed?
Observe the machine and selected auxiliaries.
What should be measured first?
Define the scope before installing sensors.
DEFINING THE SCOPE
Before selecting your configuration
Must the entire cell be instrumented from the start?
We can define an initial measurement scope and extend it to other loads later.
Can consumption per part or kilogram be compared?
Yes, when reliable production data are integrated and the measurement period and boundary are correctly defined.
Does the equipment guarantee a specific saving?
Energy provides information for identifying opportunities and verifying results. Any saving must be assessed against a baseline under comparable conditions.
LET’S DISCUSS YOUR APPLICATION
Tell us what you need to measure.
Describe your machine or cell, the auxiliary equipment and what you need to understand about consumption. We will review the information and propose an initial measurement scope.
